3 Quick Start Guide
It is recommended that all users, including those fully familiar with RF spectrum analyzers, take
a little time to read through this instruction manual before using the instrument.
However, for users who wish to get started with hands-on operation as quickly as possible, the
following may prove useful.
1. Press and hold the Power key until the screen backlight flashes. Wait a few seconds and
then check the battery condition indicator on the display. If it shows less than ¼ full the
instrument should be connected to its charger.
2. Connect the signal to be measured to the SMA connector at the top of the instrument. The
maximum allowable signal without damage is +20dBm (+127dBuV or 2.2V rms). The maximum
measurable signal is +0dBm (+ 107dBuV or 223mV rms). If there is a possibility of the signal
exceeding these levels, add suitable in-line attenuation.
3. Ensure that the Navigator keys are set to Control Markers (key illuminated green). If not
press the round key marked Control Markers. This also selects touch-screen key control.
4. Press the hard key marked Presets (Auto-Set). Select Auto Set and press Execute.
The instrument will perform a full span sweep (1MHz to 2699/1299MHz) at 0dBm reference
level and find the highest level within the sweep. It will then perform further sweeps at narrower
spans and, where appropriate, -20dBm reference level.
During this time a red background message of Status: SCANNING with be displayed. When
finished the message will become Status: COMPLETE.
When Auto Set has completed, the analyzer should be set with a fairly narrow span (typically
10MHz) centred on the signal with the M1 marker at the centre frequency and in Peak-find
mode (indicated by an upwards arrow prior to the M1 readout). RBW will be set to Auto.
5. Press Exit to return to the main menu.
The M2 marker can be turned on from the hard key marked Control Markers. Markers are
moved using the Navigator hard keys – Left/Right moves the markers, Up sets peak-find mode
where the selected marker jumps to peaks within the trace, Down sets scroll mode where the
marker moves across the screen in one pixel steps (1/270
th
of the span). The marker currently
under control is selected by the centre key (M1/M2) and indicated by an arrow before the
marker readout.
From the main menu adjustments can be made to centre frequency and span (or start and
stop), sweep mode, detector type, RBW and VBW, reference level, displayed traces and
markers.
The menu system is hierarchical with each top-line key selecting a set of five second-line
sub-menu keys. Each of these provides access to a set of keys on the bottom line that perform
the actual functions.
Context sensitive help for each sub-menu group can be accessed by pressing the hard key
marked “Status (Help)” followed, if not already selected, by Context Help. This provides
sufficient information to understand the principles of operation.
